RESUMEN

Hydrogen peroxide (H2O2) plays a pivotal role in advancing sustainable technologies due to its eco-friendly oxidizing capability. The electrochemical two-electron (2e-) oxygen reduction reaction and water oxidation reaction present an environmentally green method for H2O2 production. Over the past three years, significant progress is made in the field of carbon-based metal-free electrochemical catalysts (C-MFECs) for low-cost and efficient production of H2O2 (H2O2EP). This article offers a focused and comprehensive review of designing C-MFECs for H2O2EP, exploring the construction of dual-doping configurations, heteroatom-defect coupling sites, and strategic dopant positioning to enhance H2O2EP efficiency; innovative structural tuning that improves interfacial reactant concentration and promote the timely release of H2O2; modulation of electrolyte and electrode interfaces to support the 2e- pathways; and the application of C-MFECs in reactors and integrated energy systems. Finally, the current challenges and future directions in this burgeoning field are discussed.

RESUMEN

BACKGROUND: The pandemic has accelerated digital work transformation, yet little is known about individuals' willingness to sustain such digital modes and its associated factors. A better understanding of this willingness and its drivers is crucial for guiding the development of future digital work infrastructure, training programs, and strategies to monitor and prevent related health issues. OBJECTIVE: This study aims to quantify the general population's willingness to sustain pandemic-induced digital work, identify its associated factors, and examine how screen time moderates these relationships. METHODS: A cross-sectional study was conducted targeting Hong Kong residents aged ≥18 years who have increased engagement in digital work since the pandemic. Data were collected through self-reported, web-based surveys. Descriptive statistics determined prevalence rates, while structured multiphase logistic regression identified associated factors and explored the moderating effects of screen hour levels. RESULTS: This unfunded study enrolled 1014 participants from May 2 to June 24, 2022, and completed data analysis within 3 months after data collection. A total of 391 (38.6%; 95% CI 35.6%-41.6%) participants expressed willingness to sustain digital work. Positive factors associated with this willingness included being an employee (odds ratio [OR] 3.12, 95% CI 1.59-6.45; P=.001), being health professionals (OR 3.32, 95% CI 1.49-7.82; P=.004), longer screen hours (OR 1.09, 95% CI 1.03-1.15; P=.002), and higher depression levels (OR 1.20, 95% CI 1.01-1.44; P=.04). Conversely, negatively associated factors included older age (OR 0.87, 95% CI 0.81-0.94; P=.001), extroversion (OR 0.66, 95% CI 0.51-0.86; P=.002), higher eHealth literacy (OR 0.96, 95% CI 0.93-0.98; P<.001), perceived greater susceptibility to COVID-19 (OR 0.84, 95% CI 0.74-0.96; P=.009), residence in a high-severity COVID-19 community (OR 0.73, 95% CI 0.63-0.84; P<.001), having infected individuals in the immediate social circle (OR 0.64, 95% CI 0.46-0.88; P=.006), higher BMI (OR 0.94, 95% CI 0.90-0.99; P=.02), feelings of being out of control (OR 0.96, 95% CI 0.93-0.98; P=.002), and higher fear of COVID-19 (OR 0.96, 95% CI 0.94-0.98; P=.001). In addition, a moderating effect of screen hour level (high: >8 h/d; low: ≤8 h/d) influenced the association among 10 factors related to willingness to sustain pandemic-induced digital work, including age, education level, household size, needs for regular medical care, BMI, frequency of both vigorous and moderate physical activities, perceived COVID-19 severity, immediate social circle COVID-19 presence, and fear of COVID-19 (all P values for interaction <.05). CONCLUSIONS: The substantial willingness of the general population to sustain digital work after the pandemic highlights the need for robust telework infrastructure, thorough monitoring of adverse health outcomes, and the potential to expand telehealth services among this group. The identification of factors influencing this willingness and the moderating role of screen hours inform the development of personalized strategies to enhance digital work acceptance where needed.

RESUMEN

AIM AND OBJECTIVES: To investigate the prevalence of dysphagia in patients with COPD, identify the risk factors for dysphagia, develop a visual clinical prediction model and quantitatively predict the probability of developing dysphagia. BACKGROUND: Patients with COPD are at high risk of dysphagia, which is strongly linked to the acute exacerbation of their condition. The use of effective tools to predict its risk may contribute to the early identification and treatment of dysphagia in patients with COPD. DESIGN: A cross-sectional design. METHODS: From July 2021 to April 2023, we enrolled 405 patients with COPD for this study. The clinical prediction model was constructed according to the results of a univariate analysis and a logistic regression analysis, evaluated by discrimination, calibration and decision curve analysis and visualized by a nomogram. This study was reported using the TRIPOD checklist. RESULTS: In total, 405 patients with COPD experienced dysphagia with a prevalence of 59.01%. A visual prediction model was constructed based on age, whether combined with cerebrovascular disease, chronic pulmonary heart disease, acute exacerbation of COPD, home noninvasive positive pressure ventilation, dyspnoea level and xerostomia level. The model exhibited excellent discrimination at an AUC of .879. Calibration curve analysis indicated a good agreement between experimental and predicted values, and the decision curve analysis showed a high clinical utility. CONCLUSION: The model we devised may be used in clinical settings to predict the occurrence of dysphagia in patients with COPD at an early stage. RELEVANCE TO CLINICAL PRACTICE: The model can help nursing staff to calculate the risk probability of dysphagia in patients with COPD, formulate personalized preventive care measures for high-risk groups as soon as possible to achieve early prevention or delay of dysphagia and its related complications and improve the prognosis. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMEN

As a large and heterogeneous group of disorders, neurodegenerative diseases are characterized by the progressive loss of structure or function in neurons, finally leading to neuronal death. Neurodegenerative diseases cause serious threat to a patient's quality of life and the most common are Alzheimer's disease and Parkinson's disease. Currently, little is known of the detailed etiology of these disorders; as such, there are no effective treatments available. Furthermore, the lack of targeted, effective, and resolvable therapy for neurodegenerative diseases, represents an expanding research field for the discovery of new therapeutic strategies. Investigations of the potential pathogenesis of neurodegenerative diseases will become the basis of preventing the occurrence and development of neurodegenerative diseases and finding effective therapies. Existing theories and mechanisms, such as genetic and environmental factors, abnormal protein accumulation, and oxidative stress, are intricately associated with each other. However, there is no molecular theory that can entirely explain the pathological processes underlying neurodegenerative diseases. Due to the development of experimental technology and the support of multidisciplinary integration, it has been possible to perform more in-depth research on potential targets for neurodegenerative diseases and there have been many exciting discoveries in terms of original theories and underlying mechanisms. With this review, we intend to review the existing literature and provide new insights into the molecular mechanisms underlying neurodegenerative diseases.

RESUMEN

Objectives: Using meta-analysis to determine the effect size of the recidivism rate of participants in community correction programs that are conducted entirely in community settings. Methods: Following the Preferred Reported Items for Systematic Reviews and Meta-analyses (PRISMA), 25 qualified studies contributed 35 independent effect sizes. Results: Full participation in a program significantly reduced the recidivism rate. Participant age was a significant moderator of heterogeneity. Those aged over 18 have lower recidivism rates. Interventions that fully follow the Risk-Need-Responsivity (RNR) design principles achieved similar results to those that did not. Recidivism rates increase more than 12 months after the program ends. Conclusions: The effectiveness of community correctional programs varies depending on the participant's age. The RNR principles are not golden. The above factors should be carefully considered when conducting intervention design in the future. Results should be interpreted with caution due to the literature's high heterogeneity and low quality. Supplementary Information: The online version contains supplementary material available at 10.1007/s11292-022-09550-w.

RESUMEN

Purpose: This study develops and investigates the changes in anxiety symptoms and quality of life (QoL) among participants of the online Strength-informed Acceptance and Commitment Therapy (SACT) across three tests. METHODS: A small-scale, quasi-experiment with no control group was conducted. Repeated-measures analysis was employed to assess the changes of the three tests, which were the pre-experimental, post-test, and 3-month follow-up test. A total of 47 adolescents (ages 10-12) completed the 45-min intervention that lasted 10 weeks. RESULTS: Compared with the pre-experimental, the post-test indicated significant anxiety symptoms reduction but not a statistically significant increase in QoL. The 3-month follow-up test indicated reduced anxiety symptoms and improved QoL compared with the pre-experimental. The with-in subject changes were substantial. CONCLUSIONS: The online SACT is a promising model to reduce anxiety symptoms and promote QoL among adolescents during the current COVID-19 pandemic, which show both short- and long-term benefit to the participants.

RESUMEN

A three-stage strength-based meaning intervention (SMI) was developed in the present study, and its utility in facilitating the mental health of individuals with physical disabilities in low-income communities was tested. A randomized controlled and single-blind trial was adopted. A total of 50 qualified participants (mean age = 42.12, standard deviation = 8.68; 48% males; 26 for the intervention group, 24 for the control group) completed the pre-intervention test, post-intervention test, and three-month follow-up test. No significant difference was observed between the two groups at pre-intervention assessment . After intervention, the results in terms of strength knowledge, strength use, sense of meaning in life and mental health showed a significant improvement in the intervention group, with the changes maintained over three months except mental health. The differences in mental health between the post-intervention test and the three-month follow-up test were not significant in the intervention group. The results imply that the SMI model is a promising approach in promoting the mental health of individuals with physical disabilities in low-income communities as it promotes improved knowledge and use of strength and sense of meaning in life.

RESUMEN

The present study aimed to assist public health efforts by developing and conducting psychometric testing of a brief measure of COVID-19-related stigma among people who were potentially but not necessarily infected. All the items were generated and selected based on extensive literature review, participant interviews, and expert evaluations. The psychometric properties were evaluated through performing confirmatory factor analysis tests, exploration structure equation modeling, measurement invariance, internal consistency coefficient, composite reliability, and criterion-related validity, using a sample of 2812 adults (600 male, 2212 female; mean age = 37.23, SD = 6.17) from Hubei Province, China. A clear two-factor structure of the COVID-19-related stigma among people who were potentially but not necessarily infected (i.e., perceived courtesy and affiliate stigma) was identified through the literature review and interviews. Results suggest that the two-factor model of COVID-19-related stigma (5 items for each factor) model fit the data, and the psychometric properties were acceptable. Measurement invariance across gender was supported. A two-factor 10-item scale was finally obtained.

RESUMEN

BACKGROUND: Suicide is a global issue among the elderly. The number of older people committing suicide is proliferating, and the elderly suicide rate is the highest among all age groups in China. A better understanding of the possible protective factors against suicidal ideation is necessary to facilitate prevention and intervention efforts. The objectives of the present study are threefold. First, this study aims to examine the psychometric properties of the three-dimensional inventory of character strengths (TICS) with a sample of older adults. Second, this study intends to investigate correlations among suicide ideation, wellbeing, and character strengths. Third, the study seeks to explore the possible protective roles of the three character strengths and wellbeing in explaining suicidal ideation among older adults. METHODS: A cross-sectional study comprising 308 older adults aged at least 50 years old from nursing homes was conducted. Four questionnaires, namely, the TICS, the Geriatric Suicide Ideation Scale-10 items, the Brief Inventory of Thriving, and the Satisfaction with Life Scale, were used. Exploratory structural equation modeling, intraclass correlation coefficients, partial correlations, and sets of hierarchical regressions were adopted to estimate and report the results. RESULTS: TICS could be used to assess the character strengths (i.e., caring, inquisitiveness, and self-control) among older adults with an acceptable goodness-of-fit (chi square = 157.30, df = 63, p < 0.001, CFI = 0.94, TLI = 0.90, RMSEA = 0.07, 90% CI = [0.06, 0.08]). Wellbeing and character strengths exhibited a negative association with suicidal ideation among older adults. Moreover, character strengths showed an independently cross-sectional relationship with suicidal ideation, explaining 65.1% of the variance of suicidal ideation after controlling for the wellbeing and demographics. CONCLUSION: This study indicated that character strengths were associated with low levels of suicidal ideation. Therefore, the protective factors against suicidal ideation among older adults should be given additional attention.

RESUMEN

The present study aims to examine the comorbidity patterns of the symptoms (intrusion and avoidance) for posttraumatic stress disorder (PTSD) and generalized anxiety disorder (GAD) and the role of perceived threat and courtesy stigma in distinguishing specific patterns of the symptoms for PTSD and GAD among children and adolescents who are susceptible to coronavirus disease 2019 (COVID-19) in Hubei, China. A total of 1172 (683 female and 489 male) children and adolescents aged 8-18 years were involved in completing the measurements of PTSD, GAD, perceived threat of COVID-19, and COVID-19-related courtesy stigma. The Latent Profile Analysis identified the three profiles of the symptoms for PTSD and GAD which were labeled as Moderate PTSD, Mild Comorbidity, and Severe Comorbidity. The scores of the symptoms for PTSD, GAD, perceived threat, and stigma were different among the three profiles. The risk factors (i.e., perceived threat and stigma) that are related to comorbidity patterns were examined through a three-step method. The possibility of entry into the Severe Comorbidity Profile increased with increasing perceived threat and stigma. The mental health care interventions for children and adolescents who are susceptible to COVID-19 can be developed to reduce perceived threat and stigma.

RESUMEN

Fabrication of hybrid membranes composed of porous materials embedded in polymer matrices is a subject of topical interest. Herein, we introduce a new class of hybrid membranes: hyper-cross-linked metal-organic polyhedra (HCMOPs). These membranes are based upon soluble MOPs that can serve as high-connectivity nodes in hyper-cross-linked polymer networks. HCMOPs spontaneously form macro-scale, defect-free, freestanding membranes, and, thanks to the covalent cross-linking of MOPs, the resulting membranes possess multiple functionalities: strong water permeability; self-healing ability; antimicrobial activity; and better separation and mechanical performance than pristine polyimine membranes. This study introduces a new concept for the design and fabrication of multifunctional membranes and also broadens the applications of MOPs.

RESUMEN

PURPOSE: Although stress emerges when environmental demands exceed personal resources, existing measurement methods for stress focus only on one aspect. The newly-developed Short Stress Overload Scale (SOS-S) assesses the extent of stress by assessing both event load (i.e., environmental demands) and personal vulnerability (i.e., personal resources). The present study was designed to evaluate the psychometric properties of the Chinese version of Stress Overload Scale-Short (SOS-SC), and further examine its roles in screening mental health status. METHODS: A total of 1364 participants were recruited from communities and colleges for scale validation. RESULTS: Reliabilities were good throughout the subsamples (ω > 0.80). Confirmatory factor analysis indicated the acceptable goodness-of-fit for the two-factor correlated model (Sample 1: 560 community residents). Multi-group confirmatory factor analysis confirmed measurement invariance across community residents (Sample 1) and college students (Sample 2 and Sample 3). Criterion validity and convergent validity were established (Sample 2: 554 college students). Latent moderated structural equations demonstrated that the relationship between SOS-SC and depression is moderated by social support (Sample 2), further validating the SOS-SC. In addition, the SOS-SC effectively screened individuals in a population at different levels of mental health status (i.e., "at risk" vs. "at low risk" for depression symptoms and/or wellbeing). CONCLUSION: The SOS-SC exhibits acceptable psychometric properties in the Chinese context. That said, the two aspects of stress can be differentiated by the Chinese context, therefore, the SOS-SC can be used to measure stress and screen mental health status among the Chinese population, and monitor and evaluate health-promoting interventions.

RESUMEN

PURPOSE: Studies that focus on the development of the typology of individual strength profiles are limited. Thus, this study aimed to determine strength profiles with different health outcomes based on the Three-Dimensional Inventory of Character Strengths (TICS). METHODS: The TICS was used to measure three-dimensional strengths: caring, inquisitiveness, and self-control. A total of 3536 community participants (1322 males and 2214 females with ages ranging from 17 to 50, M = 23.96, SD = 5.13) completed the TICS. A subsample (n = 853; female = 68.2%, male = 31.8%) was further required to complete the Depression Anxiety Stress Scale and Flourishing Scale. A latent profile analysis (LPA) was conducted in the total sample to identify the latent strength profiles. Then, a three-step method was implemented to compare the mental health outcomes between strength profiles in the subsample. RESULTS: The LPA helped determine two subgroups based on the entire sample: the at-strengths group (high scores on all dimensions) and the at-risk group (low scores on all dimensions). As expected, the at-strengths group had less significant negative emotional symptoms (at-strengths group = 0.57, at-risk group = 0.83, χ2 = 33.54, p < .001) and had better psychological well-being (at-strengths group = 5.81, at-risk group = 4.64, χ2 = 276.64, p < .001). CONCLUSIONS: This study identified two character strength profiles with different health outcomes. Specifically, populations with low-character strengths (caring, inquisitiveness, and self-control) were more likely to demonstrate poor mental health outcomes. Our findings also showed that a particular trait subtype can be considered in identifying high-risk populations and further implementing targeted strength-based interventions.

RESUMEN

PURPOSE: Character strength is described as a positive and organized pattern of emotions, thoughts, and behaviors. It serves as a schema that organizes categories of information toward the self, others, and the world, and provides the self-aware knowledge that facilitates the pursuit of goals, values, and ethical principles. Recent research has suggested that three reliable factors emerge from the measures of character strengths: caring, inquisitiveness, and self-control. The goal of this paper is to develop a psychometrically sound short measure of character strength. METHODS: The questions were addressed in two studies using two independent samples: a cross-cultural (i.e., 518 Asians and 556 Westerners) sample, and a cross-population (i.e., 175 community participants and 171 inpatients) sample in China. RESULTS: Findings from the exploratory and confirmatory factor analysis suggested a cross-cultural three-factor model of character strength that could be measured by the Three-dimensional Inventory of Character Strengths (TICS). A multigroup confirmatory factor analysis further indicated that the number of factors and factor loadings was invariant in the medical and community samples. This result indicated that the brief inventory could be applied to a medical context. Internal reliability, content validity, and predictive validity were good, although the predictive validity of the three character strengths for psychological symptoms in the medical sample was more modest than that in the community sample. CONCLUSIONS: TICS is expected to be used for screening populations at risk, and a tool to aid mental health professionals in group-based treatment/intervention planning. It also should be noted that this short inventory should be used with caution for individual decision making.

RESUMEN

Strengths are positive qualities that significantly contributed to well-being of individuals and community. Therefore, a reliable and valid measure of strengths for research and practice is needed. The Brief Strengths Scale (BSS) is a newly developed tool for measuring the three-dimensional strengths model (i.e., temperance, intellectual, and interpersonal strength). However, empirical support for the measurement invariance of the BSS has not been obtained. This study examined the three-factor structure of BSS across gender, age, education, and marriage groups in a community sample (n = 375) using multi-group confirmatory factor analysis. After removing one item of each subscale from the original version, the revised model provided a good fit to the data at different subgroups. The revised nine-item BSS indicated that measurement invariance across gender and age groups was achieved. In addition, the measurement was more influenced by social-cultural factors than biological factors.

RESUMEN

OBJECTIVE: This study used a two-wave longitudinal research design to explore the role of individual strengths, including interpersonal strength, intellectual strength, and temperance strength, in affecting the mental health of stressed college students. PARTICIPANTS: A total of 404 stressed Chinese college students were screened to participate in this 12-month longitudinal study. METHODS: At the beginning of the study (Time 1), students who had not experienced stressful events within the last 12 months were invited to assess their strengths, psychological well-being, and psychological symptoms. After 12 months (Time 2), 404 students who reported stressful experiences completed the scales again and were retained for the final analyses. RESULTS: Academics-related stressors were the most endorsed life events among college students, whose states of mental health showed downward trends from Time 1 to Time 2. Three strengths had weak to modest correlations to mental health at both Time 1 and Time 2. Although the additional variances of mental health explained by the three strengths were very modest, the mediational roles of the strengths were identified. The perceived stress completely mediated the relationship between the strengths and the psychological symptoms and partly mediated the relationship between the strengths and psychological well-being. CONCLUSIONS: Individual strengths may function as a defense against perceived stress and are protective factors of mental health. These strengths maintain mental health by enhancing the psychological well-being and reducing the psychological symptoms of individuals.

RESUMEN

The present study examines the efficacy of expressive writing among Chinese undergraduates. The sample comprised of 74 undergraduates enrolled in a 9-week intervention (35 in experimental class vs. 39 in control class). The writing exercises were well-embedded in an elective course for the two classes. The 46-item simplified Chinese Self-Rated Health Measurement Scale, which assesses psychological, physical and social health, was adopted to measure the outcome of this study. Baseline (second week) and post-test (ninth week) scores were obtained during the classes. After the intervention on the eighth week, the self-reported psychological, social and physical health of the experimental class improved. Psychological health obtained the maximum degree of improvement, followed by social and physical health. Furthermore, female participants gained more psychological improvement than males. These results demonstrated that the expressive writing approach could improve the physical, social and psychological health of Chinese undergraduates, and the method can be applied in university psychological consulting settings in Mainland China.

RESUMEN

OBJECTIVE: This study aims to explore the relationship between virtues and self-disclosure via a cross-sectional study and an intervention study among Chinese. METHODS: In study one, 144 healthy individuals completed the Chinese Virtues Questionnaire (CVQ) and the short version of Jourard Self-Disclosure Questionnaire. In study two, 41 undergraduates voluntarily attended a nine-week intervention. Satisfaction with Life Scale (SWLS) was adopted as the well-being indicator. They were asked to complete the vitality sub-scale of CVQ and SWLS at week one for obtaining the virtue scores and baseline scores of well-being. After an eight-week intervention, SWLS was completed again to examine the intervention efficacy. RESULTS: Among the three virtues, only vitality had the significant and positive relation with self-disclosure. After eight weeks, the high-vitality group obtained the significant growth of satisfaction with life. The change degree of satisfaction among high vitality individuals was significantly higher than the low vitality group. CONCLUSION: Prescreening of individual vitality may be helpful for identifying the sensitive targets of expressive writing intervention. However, considering that this is a preliminary study, more rigorous randomized controlled trials will be helpful to test this conclusion in future.

RESUMEN

Triple-negative breast cancer (TNBC) is a subtype of breast cancer that carries the worst prognosis and lacks specific therapeutic targets. To achieve accurate "cargos" delivery at the TNBC site, we herein constructed a novel biomimetic nano-Trojan horse integrating chemotherapy with gene therapy for boosting TNBC treatment. Briefly, we initially introduce the diselenide-bond-containing organosilica moieties into the framework of mesoporous silica nanoparticles (MONs), thereby conferring biodegradability to intratumoral redox conditions in the obtained MONSe. Subsequently, doxorubicin (Dox) and therapeutic miR-34a are loaded into MONSe, thus achieving the combination of chemotherapy and gene-therapy. After homologous tumor cell membrane coating, the ultimate homologous tumor cell-derived biomimetic nano-Trojan horse (namely, MONSe@Dox@miR-34a@CM) can selectively enter the tumor cells in a stealth-like fashion. Notably, such a nanoplatform not only synergistically eradicated the tumor but also inhibited the proliferation of breast cancer stem-like cells (BCSCs) in vitro and in vivo. With the integration of homologous tumor cell membrane-facilitated intratumoral accumulation, excellent biodegradability, and synergistic gene-chemotherapy, our biomimetic nanocarriers hold tremendous promise for the cure of TNBC in the future.
